SELF-FIGHTING TABLE.

Specification of Letters Patent.

Patented May 9, 1916.

Application filed September 4, 1914. Serial No. 860,274.

- To all whom it may concern Be it known that I, JOHN ZAMBORA, a subject of the Emperor of Austria-Hungary residing at Maynard, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Self- Righting Tables; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention comprehends certain new and useful improvements in self righting tables and has for its primary object to provide a device of this character which will be especially adapted for use upon ships.

The invention has for another object to provide a table of this character which will be constructed in such manner that the main portion of the top thereof will be mounted upon a spherical member resting upon a stationary base of the table and having a pendulum depending therefrom and in closed in the base to assure movement of the main portion of the table top to a horizontal plane upon swaying of the vessel in either direction.

The invention has for a further object to provide a table of the above stated character which will be constructed in such manner, that the spherical member will rest in a nest formed by flaring the upper end of the frusto-conical base while the weight on the pendulum rod is adapted to swing at the off set portion of the base, thereby pro-- viding a table, the top of which may be at all times automatically retained in horizontal position.

The invention has for a still further object to provide a table of this character which will be of extremely simple and cheap construction and operation as Well as highly eflicient and durable in use.

With these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of the complete device; Fig. 2 is a top plan view thereof, and Fig. 3 is a vertical detail section through the center of the device.

Referring in detail to the drawings by numerals, l designates the frusto-conical base of the table which has its upper edge flared outwardly to form a nest 2 to receive the spherical member 3 and form a proper support for the same. The spherical member 3 is secured in any suitable manner in a suitable socket e which in turn is secured to the center of the under face of the main portion of the table top 5 and depending from the spherical member 3 is a pendulum rod 6 having the weight 7 mounted upon its lower extremity said rod 6 and weight 7 forming a pendulum which will serve to antomatically move the main portion 5 of the table top to horizontal position upon swaying of the vessel-or other device upon which the base 1 is secured, in either direction.

The spherical member 3 is inclosed and protected by acasing 8, the bottom 8 of which is rigidly secured around the upper end of the base 1, and located below the nest :2 thereof, while the circular side of said casing 8 extends upwardly from the bottom thereof inwardly of the upturned edge thereof and has a stationary inturned flange 9.

It will be understood that when the vessel or other device upon which the frusto-conical base 1 is secured is in upright position, the upper face of the outer circular stationary edge 9 of the table top will be flush with the main portion 5 thereof. It will be understood that the weight 7 may be adjusted upon the pendulum rod 6 by rotating the nut 10 threaded upon the lOWer extremity of said rod 6 in the proper direction, it being understood that the weight 7 rests upon the nut 10. It will further be seen that as the spherical member 3 rocks in the nut 2 to bring the main portion 5 of the table top to horizontal position when rocking movement of the ship or other support upon which the cable is positioned, the pendulum rod 6 will swing and the weight 7 on the pendulum rod 6 will move toward and into the outwardly offset circular portion 11 of the frusto-conical base 1 formed by pressing a portion of said frusto-conical base 1 outwardly near the lower end or bottom of said base 1. It will be understood that the outwardly off-set portion 11 extends entirely around the base 1 in order that the weight 7 on the pendulum rod 6 may swing into the same regardless of the direction in which the pendulum rod 6 is moving. 1 LT}:

l/Vhile I have shown and described the preferred en'ibodiment of my invention, it will be understood that minor changes in the details of construction, combination and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed or sacrificing any of the advantages thereof.

What is claimed is A self-righting table comprising a frustoconical base having its upper end flared outwardly to provide a nest, a horizontal member having an opening through which the upper end of the base extends, the Wallof the opening engaging the outer side of the base to support the member, a side member secured to and rising vertically from the first named member, a flange extending 1nwardly from the upper edge of said side spherical member for holding said movable member in a horizontal plane.

In testimony whereof I allix my signature in presence of two witnesses.
